clic cost schedule wg mandate
CLIC Cost & Schedule WGMandate

April 2009

  • Establish and optimize the cost of the CLIC complexat the nominal collidingbeamenergy of 3 TeV, as well as that of an optional first phase with a collidingbeamenergy of 500 GeV
  • Define and optimize the generalschedule for the 3 TeV and 500GeVprojectsdefinedabove
  • Estimate the electrical power consumption of the 3 TeV and 500 GeVprojectsdefinedabove
  • Identify possible modifications of parameters and/or equipmentleading to substantial capital and/or operationalcostsavings, in order to define best compromise between performance and cost
  • Developcollaboration with ILCproject on costestimatemethodology and cost of common or comparable systems, aimingatmutualtransparency
  • Document the process and conclusions in the CDR in 2010

clic cost schedule wg activities 2009
CLIC Cost & Schedule WGActivities 2009

April 2009

  • Establish responsibilities, procedures & workpackages in cost assessment
  • Reception specified costing tool, including currency conversion & price escalation procedures, and start applying it
  • Identify domains of analytical costing and perform estimates
  • Identify cost drivers and areas of potential cost reduction
  • Conduct first round of analytical costing of CLIC 3TeV
  • Establish proper technical/cost scaling of CLIC 500 GeV
  • Refine general schedule and derive manufacturing/reception testing/installation constraints
  • Update estimates of power & energy consumption, including part-load operation
  • Collaborate with ILC on previously defined cost topics
    • Cost risk analysis
    • Cost of normal conducting magnets

status of analytical cost estimates
Status of analytical cost estimates
  • CLIC Study Costing Tool
    • Operational
    • Based on PBS for CLIC 3 TeV and 500 GeV, as defined by TC for the CDR

⇒ analytical cost upload just started

  • Questionnaire sent to Domain/Subdomain Coordinators (3 August 2009)
    • Preparation of analytical cost estimate review
    • Identification of cost drivers, risks and reduction issues

⇒ one received so far!

  • Presentations at C&S WG meetings
    • 24 September 2009: Main beam production - damping rings (Y. Papaphilippou)
    • 29 October 2009: Drive beam production (B. Jeanneret), Two-beam accelerator modules (G. Riddone)
    • 5 November 2009: Infrastructure & services (J. Osborne)
    • 26 November 2009: Main beam production - injectors & beam transport (L. Rinolfi), [Interaction region (L. Gatignon)]

⇒ work in progress

⇒ technical definition for analytical costing not available for all domains/subdomains

main linacs are the cost drivers

Indirect impact

Direct

Main linacs are the cost drivers
  • The main linacsaccount for a large fraction of CLIC cost, and impact strongly on other capital (tunnel, infrastructure, services) and operation (electricity, cooling, maintenance) costs
  • Veryhigh, unprecedentedmultiplicity of components, willrequirenovel solutions for manufacturing, installation, maintenance, reliabilityassessment

CLIC 3 TeV (per linac)

Modules: 10462

Accelerating str.: 71406 PETS: 35703

MB quadrupoles: 1996 DB quadrupoles: 20924

CLIC 500 GeV (per linac)

Modules: 2124

Accelerating str.: 13156 PETS: 6578

summary
Summary
  • Costconsciousnesswellestablished in CLIC technicalworking groups (Module, RF structures, CES,…)
  • Somecost drivers and costreduction areas identified - as well as theirinterplay - analysis not yet exhaustive
  • Costscalingmodelsonlyexist for limitednumber of components or subsystems
  • Analyticalcostingexerciseunderway by domaincoordinatorswith input fromtechnical system experts, in domainswheretechnicalbaselineexists
  • Technicalbaseline to bedefined in otherdomains
  • Significantdifferencesobserved w r to 2007 costestimate
  • Feedback provided to technical system design
  • Targetedcoststudies by industrialcompaniesconsidered, in particular for large-series components
  • Reliability/availabilityassessment to beconducted (TC?) for system design and possible cost impact
